Jalen McMillan was a good one-two punch for the Huskies this season when paired with either Rome Odunze or Ja'Lynn Polk. He has good speed and explosiveness which are traits that you see more and more receivers have in the league. He also have a good feel for space on the field and is a solid route runner.
The Panthers are most likely going to spend a lot of draft capital on the offensive line this year. Bryce Young needs protection, but when he has that protection he needs someone to throw to. Adam Thielen was Young's favorite target, but he needs more.
I think McMillan would be a great addition to this team, he can stretch the field with his speed and has good hands. I also believe that having a younger receiver to create chemistry with would be good for a young quarterback like Young.
